Overwhelmed and depressed

I have had a lot of battles throughout life-diagnosed with a language processing disorder, raped at 19, etc.
I just recently had a colonoscopy. The Dr. is pretty sure I have Chron's. I am waiting on biopsy results but will have to wait a few more days until I get results. I know I shouldn't worry because I haven't received a confirmation yet. However, I am very overwhelmed right now and am getting married in July. One of my many Dr.s said they want to put me on predisone for 6 weeks on a really high dose. I am completely opposed to predisone. It makes me feel terrible. I was on it 5 days and couldn't stand it. It gave me a terrible head aches, cramps, and made me gain weight.
In addition to having stomach pains. I have nodular episcleritis in my eye (making my eye look blood shoot), erythema nodosum that I have been battling with since freshmen yr in h.s. (I counted 27 nodules on my legs the other day), hemroids, a swollen tongue, chest pain when I eat, and another issue which I don't feel comfortable posting.
I am feeling so depressed right now. I am supposed to be enjoying this time leading up to my wedding but instead I feel sick and miserable thanks to whatever is going on medically.

Thank you for the response it is greatly appreciated. I wish I had a counselor to talk to but unfortunately can't afford it. I have so many medical bills right now (in addition to saving for a wedding) that my budget just doesn't allow it. I feel very helpless and depressed.

Why are they wanting you on high dose of prednisone? I have crohns disease and it can be difficult at times but look at it this way it could be a lot worse. I have dealt with it for about 10 years I have had one resection. It will be ok. Try for other maintance meds.
